Andrew Herxheimer (4 November 1925 – 21 February 2016) was a German-born British clinical pharmacologist. He was "interested in all aspects of providing independent, unbiased, clear and concise information about therapeutic interventions to professionals and the public, and [had] a long experience of observing the pharmaceutical industry at work". He is known for founding Drug and Therapeutics Bulletin, to better educate medical providers on prescription drugs. After retiring from his academic career at London Hospital and Charing Cross in 1991, he continued his career as a consultant for the Cochrane Collaboration with a focus on adverse drug effects, and as an internationalist in patient advocacy and consumer advocacy.
